Abstract: A management system may test network paths prior to scheduled calls. Testing network paths may include one endpoint placing a test call to an endpoint on the other end of the path. Various characteristics of the network path may be tested. If the network path fails and/or in some way does not meet the predefined characteristics for the call, an administrator may be notified and/or alternate network path may be detected and tested. The call may be rescheduled if a satisfactory network path is not found in time.

Abstract: In various embodiments, a management system may query connection devices for their capabilities and store the information in a data structure. In some embodiments, the data structure may be in a form of a Deducible Capability Numbering (DCN) number. In some embodiments, the DCN number may describe the capabilities of a connection device using a series of representative numbers. After connecting the connection devices, the management system may continue monitoring capabilities of the connection devices and line failures. The management system may reconnect connection devices based on their capabilities if a line failure occurs.
